Hitachi ZX135-7 Excavator with Custom Arm
This project involved the development of a detailed 3D model of the Hitachi ZX135-7 excavator, customized with a specialized arm configuration and forestry attachment system.
The objective was to accurately recreate the modified mechanical structure while maintaining production-ready geometry suitable for visualization, animation, and industrial presentations.
Custom Engineering Focus
Unlike standard equipment modeling, this project required:
- Custom arm redesign
- Hydraulic routing adjustments
- Attachment integration (grapple system)
- Structural alignment for pivot accuracy
- Mechanical clearance validation
All custom components were modeled to reflect realistic joint behavior and industrial functionality.
Modeling Scope
- Full excavator exterior modeling
- Undercarriage and track system detailing
- Cabin exterior & interior base structure
- Custom arm assembly
- Engcon tilt-rotator system
- Hydraulic cylinders and hose detailing
The mechanical hierarchy was structured for potential rigging and animation workflows.
Technical Specifications
- Clean quad-based topology
- Subdivision-ready surfaces
- Real-world scale accuracy
- Optimized mesh density
- Organized object grouping
- PBR-ready UV structure
The model balances geometric precision with performance efficiency for rendering and real-time adaptation.
